Description

Wall surface sticking piece and its disassembling device

Technical field

The present invention relates to a wall sticking part and its disassembling device, in particular to a dismounting device that can completely disassemble a sticking part from a wall surface and a wall sticking part that can be matched with it.

Background technique

In general residential or office environments, after the decoration is completed, if you need to add storage products or accessories, you usually need to install additional fixing devices. For the installation of the fixing device, it is often necessary to use iron nails to fix it, or to drill a hole on the wall to install an expansion screw (gecko), and then use the screw to lock the fixing device on the expansion screw. Although this installation method can be strong and stable to install and store products, it is more difficult to construct, and it will leave irreversible damage marks at the installation position.

In order to solve the problems of construction difficulties and damage, some manufacturers have developed adhesive fixing devices. The fixing devices are adhered to the wall surface to be installed with glue, and storage products or other accessories can be installed. When the installation position is to be changed, or the product or accessory is no longer used, the adhesive fixing device only needs to be removed from the original position without leaving holes or defects on the wall surface.

Adhesive fixing devices must have sufficient adhesive force in order to provide a stable fixing ability. However, the adhesive with strong adhesive force often breaks the fixing device when removing the adhesive fixing device, and it also causes residual glue that is difficult to remove on the surface to which it is stuck.

Various sticky hooks, containers, plates or racks currently sold on the market are fixed on the wall, in which adhesive sheets (such as various foam adhesives, various pressure-sensitive adhesive films) are attached to the back On the wall; the product will be damaged when it is removed, and the adhesive film will be broken, and there will be adhesive residue on the wall that is difficult to remove. For this reason, the inventor once developed an adhesive-type holder disassembling device and applied for a patent (authorized announcement number CN 207297604 U). After use, there are still some imperfections, because it is an adhesive-type fixing device. The device needs to be able to be pasted on a variety of wall surfaces, because the material and surface conditions of each wall surface will be very different; for pasting on different walls, some may not stick very tightly, but some may stick very tightly. Some are easy to disassemble, some are not easy to disassemble, but as far as the product is concerned, it should be universally applicable. It is ideal to be easy to use in various situations.

Summary of the invention

In view of this, the inventors conducted experiments and research and came up with the following findings, conclusions and inventive concepts: 1. The strength of the molecular structure of the adhesive used should be far greater than its adhesion to any wall surface to ensure disassembly The adhesive glue will not break or break (broken glue will remain on the wall and become residual glue, which is not easy to remove), and it can be reused repeatedly. Some existing removable adhesives, strong non-marking double-sided adhesives, acrylic adhesives (also known as acrylic substrates or acrylic foams) in the viscose market can be used. 2. Applying a continuous and stable pulling force can pull the adhesive from the wall more efficiently. Therefore, the present invention is provided with a spring; the spring is applied with force to store the potential energy in the spring, and then the spring is continuously applied to the wall adhesive Applying a force to lift it up, after a period of time, the adhesive glue that sticks the adhesive piece to the wall will be pulled off the wall by continuous but not necessarily large pulling force. 3. The complexity of the structure of the disassembly device will increase, and the size will increase. The wall sticker and its disassembly device should be separated on the product, and the two should be fixedly connected when the product is to be disassembled, so that the product is manufactured and purchased And it is more convenient to use. 4. When the adhesive tape of the adhesive piece is completely pasted on the wall, the external force to pull it away will easily be dispersed to a large pasting area, so the adhesive is not easy to be pulled away from the wall , And the wall paste will stay on the wall steadily, but when a part of the adhesive starts to be pulled away from the wall, the remaining adhesive on the wall will quickly be pulled away from the wall; To make the whole piece of adhesive begin to have adhesive that has been pulled away from the wall, so as to start the process of separating the adhesive from the wall as soon as possible. When the adhesive is still fully adhered to the wall, it is necessary to provide an additional Therefore, a start spring is provided in the structure of the present invention; it is a spring with greater elasticity, which can provide an additional greater force when the adhesive starts to leave the wall; and, there is also a structure that can Apply force directly to the wall surface by twisting the threaded part, and directly apply force to slightly lift the sticking part to force the glue to partially separate from the wall surface. 5. In order to make it easier for the whole piece of adhesive to begin to separate from the wall, the force should be concentrated in a smaller local area, so that the local area of the adhesive will be pulled away from the wall with a strong tensile strength and detach first For the wall surface, the better choice is to apply force to the edge or corner of the glue; since the force of the disassembly device on the wall surface adhesive piece provided with the glue is on the connecting part B, the connecting part B is set At the edge or corner of the wall pasting part, the glue can be lifted from the edge or corner, so that the remaining glue still pasted on the wall is quickly pulled away from the wall. 6. When a part of the adhesive starts to be pulled away from the wall, the remaining adhesive that is close to the place where it is pulled away but still pasted on the wall will be quickly pulled away from the wall; in order to cause the adhesive to be pulled away from the wall in advance In order to start the process of separating the adhesive from the wall as soon as possible, there is a local glue-free area at the connection part B or where the adhesive will be pulled away from the wall at the earliest. When the wall adhesive starts to leave the wall under force , Can make the glue close to the glue-free area leave the wall with a more concentrated force; in addition, the surface of the wall sticking part is provided with a recessed area so that the glue located in the recessed area can be pasted The wall surface is relatively weak, so as to facilitate the start of disassembly of the wall surface adhesive member, and the recessed area is provided at the position where the adhesive can be separated from the wall surface first when the wall surface adhesive member is removed. 7. For the adhesive piece that is very firmly pasted on the wall, to pull it off the wall, as long as there is a spring to provide a moderately small and continuous pulling force, it can be pulled down after a period of time; this is because The force is small, and the structural strength requirements of the wall adhesive and its disassembly device can be relatively small, which is advantageous in design.

In the following, with regard to the structure and technical content of the wall surface adhesive and its detaching device related to the present invention, applicable examples are listed and described in detail with reference to the accompanying drawings; however, the present invention is of course not limited to all The listed embodiments, drawings or detailed descriptions are only.

Furthermore, those skilled in the art should also understand that the examples and accompanying drawings are only for reference and explanation, and are not intended to limit the present invention; modifications that can be easily implemented based on the description Inventions completed by modifications or changes are also deemed to be within the scope not departing from the spirit and intent of the present invention, and of course the inventions are also included in the claims of the present invention.

The following examples are given to illustrate the present invention. The present invention uses a spiral drive body 2 to drive a spring to lift and detach the adhesive piece 1 pasted on the wall from the wall. The spiral drive body 2 is composed of a fixed threaded part 21 and a movable threaded part. 22 composition, when the movable screw member rotates relative to the fixed screw member, it can be extended, thereby achieving the effect of disassembling the pasted member.

Figure 1 is an exploded schematic diagram of the embodiment. In this figure, two different structures are drawn for the connection of the tubular part of the fixed threaded part and the wall pasting part, and one is drawn on the upper right and the bottom left of the exploded view respectively. Piece 1 (the two are upside down); the first implementation structure is drawn on the upper right in the figure: the connecting part A (3) connected to the tubular part 211 is in the shape of a fork (extending upward) with a U-shaped notch 31, The connecting portion B (11) on the wall pasting piece is a T-shaped bump 111. This fork-shaped connecting portion A (3) can be inserted into the neck 1111 of the T-shaped bump to achieve the connecting portion A and the connecting portion. B connection, that is, the fixed threaded part 21 is connected with the wall pasting part 1 on the upper right side; the second implementation structure is drawn on the lower left in the figure: the connecting part A connected to the tubular part 211 is rod-shaped 3 (downward Protruding), and the connecting portion B (11) on the wall pasting piece is a bump with a hole 112. The rod 3 can be inserted downwards into the hole 112 to achieve the connecting portion A (3) and the connecting portion B (11) Connection, that is, the fixing screw 21 and the wall surface sticking part 1 on the upper right side are connected. In the implementation of the above two connection embodiments, you can choose one instead of both at the same time; in addition, in the implementation, the tubular part 211 of the fixing screw can be fixed by the fixing screw 323 and the upper right in the figure. The fork-shaped connecting connector 3 is connected and connected to the rod 3 at the bottom left in the figure at the same time. It can also be connected with one of the two; no matter what the above implementation choices are made, as long as the connecting part A and the connecting part B are connected, they will reach it. The purpose of the connection is to make the fixed screw member 21 detach from the wall surface together with the wall surface adhesive member 1 when being pushed away from the wall surface (please refer to FIGS. 7 to 11).

For the connection between the fixed threaded part 21 and the wall surface sticking part 1, that is, the connection between the connecting part A and the connecting part B, there can be many ways, such as various kinds of conventional plug connection, buckle connection, overlap connection, hook connection, hook connection, etc. The connection method is feasible as long as the above-mentioned connection purpose can be achieved. Furthermore, it is also feasible if the fixing screw 21 and the wall surface sticking member 1 are integrally formed, and it does not deviate from the scope of the spirit and intent of the present invention.

Figures 2 to 5 clearly show the shape, composition and relationship of each part of the wall pasting element and its disassembly device according to the present invention in cross-sectional and plan views after assembly. Among them, the fixed threaded element 21 is a tubular portion 211 extending in a tubular shape. There are three screw hole posts 212 at the end. The base frame 32 is fixed to the screw hole posts 212 by the three fixing screws 323 passing through the screw holes 322. Because the connecting part A (number 3 in the figure) extends from the base frame Therefore, the connecting part A 3 is fixed to the fixed threaded part 21; on the wall surface sticking part 1, (Figure 5) the connecting part B 11 has a neck 1111 which can be matched with the U-shaped notch, so that the connecting part A can be connected to Part B is plugged together; in addition, the tubular end of the fixed threaded member extends laterally with a rod-shaped connecting part A ("3" at the bottom left of Figure 1 and Figure 2), which can be attached to the wall surface with a hole on the part 1 The bump-shaped connecting portion B of 112 is connected. The two different connecting parts A described above can be connected to the two different connecting parts B respectively, so as to achieve the connection between the fixed threaded part 21 and the wall surface sticking part 1.

The wall adhesive 1 can be connected to the supporting part 14. The supporting part 14 can be a hook shown in FIG. 1, or various suitable containers, plates, or racks, etc., which are fixed to the wall, and the bottom 13 of the adhesive 1 is fixed. There is glue 12, and by sticking the glue 12 to the wall surface W, the glue 12 can be fixed to the bottom surface 13 of the sticking member in an adhesive manner, or can be fixed to the bottom surface 13 by any other applicable conventional method.

In the figure, the thread of the fixed threaded part 21 is a female thread, the thread of the movable threaded part 22 is a male thread, and the female thread and the male thread are matched threads; in the figure, the movable male threaded part 22 is provided with The hand wheel 222 has a large diameter and has anti-slip bumps on the circumference for easy grasping, and the slender and slightly tapered hand wheel 223 with anti-slip bumps on the surface to make it easy for the fingers to pinch the rotating thumbwheel 223. When the resistance is small, When you want to rotate quickly, pinch your fingers and rub the thumb wheel 223 to quickly rotate the male thread. You can also use a pen or a suitable rod to insert it into the insertion hole 224 as shown in Figure 1 to rotate. When the resistance is large, you can grasp it. When the handshake wheel 222 rotates, when the resistance is greater, a rod or a suitable plug can be used as the external insert 2241, and inserted into the plug hole 224 on the circumference of the hand wheel 222 in FIG. 1 to facilitate rotation.

A concave hole 221 is provided on the axis of the movable screw member 22, and a spring 41 with a thin and long diameter is accommodated in the hole. The spring has a small elastic force and a long stroke. A spring guide post 411 is provided on the axis of the spring 41. , The spring guide post 411 is connected with the pushing part 5 and can be guided when the spring expands and contracts; there is a starter spring 42 with a thicker and shorter diameter around the spring 41, which has a larger spring force and a short stroke. The spring 41 and the starter The spring 42 is a helical spring and the direction of rotation is opposite, so that if the two touch each other, they can still expand and contract smoothly.

Both the spring 41 and the start spring 42 can push the pushing part 5 to push it toward the wall surface W. The other end of the spring 41 is pushed by the bottom 2211 of the recess to obtain a driving force, and the other end of the start spring 42 is driven by the end of the movable screw member. 225 push to get driving force. Between the outer periphery of the spring 41 and the inner circumference of the activation spring 42, there is an auxiliary pushing portion 51. The auxiliary pushing portion 51 can be pushed by the end 225 of the movable screw member to push the pushing portion 5 toward the wall surface W. The function of the part 51 is to directly transmit the pressing force of the movable screw 22 to the push part 51. In the figure, the auxiliary push part 51 is drawn as a tube, and according to its function, several pillars can be arranged at the circumferential position of the tube. It is also feasible to directly transmit the pressing force of the movable screw member 22 to the pressing portion 51 appropriately such as a support.

In order to achieve the direct transmission of the pressing force of the movable screw member 22 to the pressing portion 51, the auxiliary pressing portion 51 may not be provided, and after the activation spring 42 is compressed and combined, the continuous pressing of the movable screw member 22 is directly The compressed start spring 42 is transmitted to the pusher 51. The compressed starter spring 42 serves as an auxiliary pusher 51. However, the spring is compressed and is prone to fatigue. Therefore, an auxiliary pusher 51 is provided and the Its length (that is, the length of the tube in the figure) is slightly larger than the compression height of the activation spring 42 so as to prevent the activation spring 42 from being compressed.

The pushing portion 5 has a tubular extension to form a cylindrical shape 52 as a whole. In the figure, the spring 41, the auxiliary pushing portion 51, and the activation spring 42 are all arranged in the cylindrical body 52 of the pushing portion; the movable screw member 22 can be extended into the cylinder 52 during the pushing action; the spring guide post 411 is located on the axis of the cylinder 52 and is connected to the pushing part 5; the cylinder 52 of the pushing part can be in the tubular part of the fixing screw The part 211 is stretched and retracted. The mouth of the cylinder 52 has a flange 521. When the cylinder 52 is completely extended from the through hole 321 of the pushing part under the tubular portion (Figure 2), it can be penetrated by the hole of the through hole 321. The edge 3211 blocks and does not fall off.

During use, please refer to the cross-sectional views of Figures 6 to 11 for the state of its movement and structure. The force for the wall surface sticking member 1 to break away from the wall surface is provided by the pushing portion 5, which protrudes toward the wall surface, and lifts the wall surface sticking member 1 so that the glue 12 is pulled away from the wall surface. Figure 6 is not yet in use, the structure is in a relaxed state, the movable screw member 22 reverses the fixed screw member 21, (the movable screw member 22 and the fixed screw member 21 are matched, and the forward rotation can make the movable screw member 22 extends downward to the wall W, and reverses to move upward) has retracted to its most retracted (ie upper end) position, the spring 41 and the activation spring 42 are in a relaxed state without pressing the pushing portion 5, and the pushing portion 5 is not Extend downwards, if connecting part A 3 and connecting part B 11 are to be connected at this time, the connection operation can be facilitated without hindrance.

Since the resistance is small at the beginning of use, you can use your fingers to twist the thumb wheel 223 forward to make the movable male threaded part 22 quickly and forwardly rotate, so that it starts to move down quickly, as shown in Figure 7, the male threaded part The bottom of the concave hole 2211 starts to push the upper end of the spring 41 downward, and the lower end of the spring 41 downwardly applies a force to the pushing portion 5 to push the wall surface W. The adhesive 12 fixed to the bottom surface 13 of the adhesive piece sticks the adhesive piece 1 to the wall surface. (Please refer to Figure 2), and the fixed threaded part 21 is connected with the wall adhesive part 1 to prevent the pushing part 5 from extending downwards, so that the spring 41 is compressed, and its elastic force is stored in the spring 41; the spring 41 continues to be After compression, the force pushing the wall surface W continues to increase, that is, the force pulling the adhesive 12 away from the wall surface continues to increase.

When the movable male screw 22 continues to be rotated in the positive direction to continue to move downwards, after the spring 41 is further compressed, its rebound force gradually increases, and it requires a greater force to rotate the movable male screw 22. Fingers pinch the thumbwheel 223 to turn, it will gradually become difficult to rotate, at this time, it should be changed to hold the handwheel 222 to rotate, so that a larger force can be applied to continue to rotate smoothly, so that the movable male screw 22 continues to rotate Lower compression spring 41.

The compression force received by the spring 41 will press the pushing portion 5, which is equal to the force of the pushing portion 5 protruding to the wall surface W (the activation spring 42 and the auxiliary pushing portion 51 have not yet added the pushing pushing portion 5 If the wall surface adhesive 1 is not tightly adhered to the wall surface W due to the wall material, surface condition, or poor operation, (please refer to Figure 2), push it toward the wall surface at the above-mentioned pushing part 5. During the topping process, if the pushing force received by the pushing portion 5 can overcome the adhesive force of the adhesive 12 to stick the adhesive piece 1 on the wall surface, the pushing portion 5 can extend to the wall surface W through the through hole 321 to lift the wall surface adhesion. At this time, the hand wheel 222 can continue to be rotated smoothly and positively until the male screw 22 and the pushing part 5 are fully extended to the wall surface to completely lift the wall sticking part 1 (please refer to FIG. 11). If the sticking of the wall sticking part 1 is strong enough, and the pushing portion 5 does not have enough strength to extend to the wall through the through hole 321 to lift the wall sticking part, the movable male threaded part 22 will continue to move downward to reach the position shown in FIG. At this time, the movable male screw 22 starts to contact and compress the start spring 42. The start spring 42 is a spring with a relatively large elastic force. When compressed, it can greatly increase the pressing force of the pressing portion 5. As mentioned earlier, it is particularly difficult to pull a whole piece of adhesive off the wall at the beginning, and extra force is required. When a part of the adhesive starts to be pulled away from the wall, the rest is still attached to the wall. The adhesive will be quickly pulled away from the wall. The start spring 42 is set to meet this need, and can provide extra elastic force to enter the process of separating the adhesive from the wall as soon as possible.

If the glue 12 sticks firmly to the wall, after the activation spring 42 is compressed, the elastic force of the spring 42 plus the elastic force of the spring 41 is still not enough to make the pushing portion 5 protrude from the through hole 321, and immediately starts to lift the wall surface to stick. At this time, continue to rotate the movable threaded member 22 in the positive direction, so that it continues to move downward to reach the position shown in Figure 9. At this time, the spring 41 and the activation spring 42 have been compressed to their stroke limit, and the movable male The lower end of the threaded member 22 starts to contact downwards and push the auxiliary pushing part 51. Because the auxiliary pushing part 51 is a hard object against the pushing part 5, the pushing auxiliary pushing part 51 is equal to directly pushing the pushing part 5 ; When the movable screw 22 moves down again, the pushing portion 5 will inevitably be pushed down through the through hole 321 to extend to the wall, and forcibly lift the wall sticking member 1, at this time to rotate the movable screw 22 may resist If it is not easy to rotate by hand, you can find a suitable external insert 2241 similar to the upper end of FIG. 1 and insert it into the insertion hole 224, so as to apply greater force to rotate the movable screw member 22.

When the movable screw member 22 continues to move downwards, as shown in FIG. 10, the pushing portion 5 is forced to protrude toward the wall surface W, and the fixed screw member 21 and the connecting portion A 3 are lifted up. The connecting part B 11 is connected, and the wall surface adhesive piece starts to be forced to lift up, and the adhesive 12 is in the process of separating from the wall surface.

When a part of the adhesive 12 starts to break away from the wall, it is easy to continue to expand the area that it breaks away from the wall, and then all of the glue 12 is quickly separated from the wall.

When the movable screw member 22 has fully extended toward the wall surface, and the movable screw member 22 has rotated forward to the end and no longer rotates, the wall surface adhesive member 1 is also forced by the pushing portion 5 and starts to lift, that is, it enters into the pasting. The glue 12 is separated from the wall surface, and then the activation spring 42 will release a strong elastic force, and the elastic force of the spring 41 accelerates the early process of lifting the wall sticker 1; the extension of the activation spring 42 causes the pushing portion 5 to further extend toward the wall, etc. After the activation spring 42 is fully opened, the wall adhesive 1 has been further lifted away from the wall, and a part of the adhesive 12 has been separated from the wall. At this time, the adhesive remaining on the wall is easily pulled away from the wall.

At this time, the stroke of the wall adhesive 1 away from the wall, although the unfinished part is still long, it only needs the spring 41 with a small elastic force and a long stroke to make it spring from the compressed state to provide continuous and stable Force, the pushing part 5 is extended to the wall at a stable speed, and the wall sticking piece 1 is gradually lifted from the wall. During the process, the glue 12 stuck on the wall is pulled away from the wall to complete the wall smoothly. The sticking piece 1 is completely lifted away from the wall surface, and is in the state shown in FIG. 11.

The above-mentioned starting spring 42 and auxiliary pushing portion 51 can be selected and implemented according to the product requirements during implementation, and the two can be alternatively provided, that is, only the starting spring 42 is provided in the disassembly device without the auxiliary pushing portion 51 , Or only the auxiliary pushing portion 51 is provided without the starting spring 42; the starting spring 42 and the auxiliary pushing portion 51 can also be provided in the disassembly device at the same time, or both are not provided.

The main purpose of the present invention is to pull the glue that sticks the sticking part on the wall away from the wall; since it is particularly difficult for the glue to be pulled away from the wall at the beginning, although the springs, start springs and springs have been installed in the disassembly device as mentioned above. Auxiliary pushing part, but it is still difficult to pull the glue away from the wall surface for the glue that is very firmly adhered to the wall. Therefore, the present invention further provides the following auxiliary methods and structures to make it easier to pull the glue away from the wall surface. Auxiliary methods and structures can be selected and implemented in part, or all can be selected and implemented.

(Refer to Figures 2, 3 and 11) To pull away the adhesive 12 stuck on the wall, avoid spreading the force over a large area and reduce its strength, and apply force to a smaller area; as far as the wall adhesive 1 is concerned, Applying force to the adhesive located at the edge or corner of the surface has the effect of making the force more concentrated at the edge or corner; the force is provided by the disassembly device of this case through the connecting part on the adhesive member 1. B11 is transmitted to the adhesive 12, so the connecting portion B 11 is set near the edge or corner of the wall surface adhesive 1 (the connecting portion B 11 shown in Figure 3 is located in the middle of the left side of the adhesive 1, but it can also be provided. At the upper left corner or lower left corner of the sticker 1), the edge or corner can be lifted by applying concentrated force to the edge or corner at the beginning of lifting.

(Refer to Figures 2 and 3) On the surface of the adhesive 12, there is a local glue-free area 121 at the position of the neck 1111 of the connecting part B11. There is no glue on the wall surface of the wall W at the position of the glue-free area. The glue area 121 may lack glue in the glue area as shown in the picture, or stick a covering film on the surface of the glue-free area to isolate the glue from the wall and no glue can stick to the wall. The force applied to the adhesive 12 by the detaching device in this case is transmitted to the adhesive at the neck 1111 of the connecting part B11 through the adhesive member 1 there. When the adhesive member 1 is stressed and starts to take the adhesive 12 away from the wall Since the bottom surface 13 of the sticker 1 directly located at the neck 1111 is the glue-free area 121, the force to pull the glue away from the wall is aimed at the glue near the glue-free area 121, especially in the glue-free area. The glue sticking to the wall on the edge of the zone is pulled away, because the force pulling away from the wall is concentrated on the glue close to the glue-free zone 121, so it is easier to pull the glue away from the wall first. In FIG. 3, only one glue-free area 121 is drawn, but two or more glue-free areas can also be provided during implementation.

(Refer to Figure 3) In order to make it easier for the glue to be pulled away from the wall surface, the shape of the glue-free area 121 is designed to have an appropriate sharp corner 122. The sharp corner 122 of the glue-free area can protrude inward as shown, or it can be Protruding outwards, the aforementioned force pulling away from the wall will be more concentrated at the sharp corners, making it easier to be pulled away from the wall first.

When the disassembling device in this case applies force to disassemble the wall adhesive, in order to make it easier for the adhesive to be pulled away from the wall, a recessed area 15 can be provided on the wall adhesive 1 on the bottom 13 where the adhesive is applied (refer to Figures 2, 3, and 5). And 11), the recessed area 15 on the surface of the sticker is a shallow recess on the flat bottom surface 13 to which the glue is fixed. For the adhesive 12 with uniform thickness, the surface of the sticking wall will also be in the recessed area 15. Follow the depression (shown at 123 in Figure 11), when the adhesive 12 is pasted to a flat wall, the flat surface of the adhesive 12 is pasted on the flat wall, because the adhesive 12 is soft and can be squeezed Therefore, continue to press the adhesive to make the surface 123 that is recessed following the recessed area 15, or it can touch the flat wall and stick to the wall. Because the adhesive 12 is soft and stretchable, so no matter how it is stuck The flat surface or the concave surface of the glue 12 will be pasted on the flat wall. However, the glue in the concave area 15 of the paste piece is separated from the flat wall surface due to the large distance between the surface of the concave area 15 and the flat wall. The glue at the position is always in a stretched state (123 in Figure 2 shows this situation), and its adhesion to the wall will be relatively weak. When the glue 12 is pulled away from the wall, the glue here is relatively Easy to be pulled away from the wall.

In order to set the recessed area better, the method of selecting its position is to assume that there is no such recessed area on the sticking part, and when the wall sticking part is removed from the wall, there is glue in a certain place on the sticking part. Will leave the wall first, then choose the place where the glue will leave the wall first to set a recessed area.

With reference to Figures 2, 3, 5, and 11 of the embodiment, when the connecting portion B 11 is pulled away from the wall surface, first, the place where the adhesive 12 receives the greatest force is the center on the left and the edge 123 on the left in Figure 3, even if there is no The recessed area 15, the left side of the wall surface adhesive 1 of FIGS. 2 and 3, and the adhesive 12 will all be lifted off the wall first, so the recessed area 15 is made into a long strip, in Figure 3 from the top to the bottom of the wall surface adhesive 1 On the left edge, Fig. 11 shows that the adhesive 12 covering the bottom surface of the sticker 1 is also recessed at the recessed area 15, forming an adhesive area 123 with a weaker wall surface. This area is located on the left side of the sticker 1. The edge of the strip, in this way, is easier to pull the left side of the adhesive 12 away from the wall during disassembly.

To form the adhesive 12 where the adhesive wall is not firmly adhered locally, it can also be partially covered, which is to use a thin layer of adhesive or double-sided tape with a lower viscosity to cover the small area where the adhesive force needs to be reduced. 123 To reduce the adhesion to the wall surface, or use a porous film or net to cover the surface of the small area 123 that needs to reduce the adhesion, so that the adhesive 12 can only be in contact with the wall at the holes of the film or net, by Reduce the sticking area and reduce the sticking force with the wall; as mentioned above, cover with a low-viscosity adhesive layer or hole film to form a lower sticky
